TLK2541PFP Equivalent & Substitute Parts

Part Overview

The TLK2541PFP is an 80-HTQFP transceiver manufactured by Texas Instruments, designed for interface applications. This component operates within a supply voltage range of 2.3V to 2.7V and supports operating temperatures from -40°C to 85°C. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLK2541PFP is determined by alignment of the following critical parameters:

• Supply Voltage Compatibility: Both main and substitute parts must operate within 2.3V to 2.7V
• Operating Temperature Range: Substitute parts must support -40°C to 85°C
• Mounting Type: Surface mount technology required
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status maintained
• Manufacturer: Texas Instruments as primary source
• Moisture Sensitivity Level: MSL 3 (168 Hours) classification

The TLK2501IRCP qualifies as a substitute based on these parameters. While the TLK2501IRCP operates at higher data rates (2.5Gbps) and uses a different package format (64-HVQFP versus 80-HTQFP), it maintains electrical compatibility through identical supply voltage ranges, operating temperature specifications, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The TLK2501IRCP is the manufacturer-recommended substitute for the obsolete TLK2541PFP. Both components maintain identical electrical specifications for supply voltage (2.3V ~ 2.7V) and operating temperature range (-40°C ~ 85°C), ensuring functional compatibility in equivalent circuit applications.

The TLK2501IRCP carries active product status, providing ongoing manufacturer support and availability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

Package differences exist between the two components: the TLK2541PFP uses an 80-HTQFP (12x12) package, while the TLK2501IRCP uses a 64-HVQFP (10x10) package. PCB layout modifications are required to accommodate the different pin counts and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can the TLK2501IRCP directly replace the TLK2541PFP without circuit modifications?

A: Electrical specifications for supply voltage and operating temperature are compatible. However, the different package formats (80-HTQFP versus 64-HVQFP) and pin counts require PCB redesign and layout modifications.

Q: Are there compliance differences between the main part and substitute?

A: Both components maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels are identical at MSL 3 (168 Hours).

Q: What is the primary advantage of selecting the TLK2501IRCP?

A: The TLK2501IRCP carries active product status, ensuring continued manufacturer support, availability, and supply chain reliability compared to the obsolete TLK2541PFP.

Q: Do both parts require identical supply voltage levels?

A: Yes. Both the TLK2541PFP and TLK2501IRCP operate within the 2.3V to 2.7V supply voltage range.

Q: Are there functional differences between these components?

A: The TLK2501IRCP is specified as a 2.5Gbps Serializer/Deserializer with defined input/output configurations, while the TLK2541PFP is classified as a general transceiver. Functional compatibility depends on specific application requirements and signal specifications.
